Transpiration is the loss of water from the leaves of plants. The stomata of leaves must open to allowcarbon dioxide to enter the leaf for photosynthesis, but when they are open, water vapor escapes intothe atmosphere.HYPOTHESIS: As the intensity of light is increased, the rate of transpiration will increase, asmeasured in by the loss of mass of the plant.Independent variable:Dependent variable:
Determine the rate of a reaction that follows the rate law:rate = k[A]”[B]", where:k= 1.5[A] = 1 M[B] = 3 Mm = 2n = 1

A food is initially at a moisture content of 90% dry basis. Calculate the moisture content in wet basis

Answers

Answer:

Moisture content in wet basis = 47.4 %

Explanation:

Moisture content expresses the amount of water present in a moist sample.Dry basis and wet basis are widely used to express moisture content.

The next equation express the moisture content in wet basis:

$MC_(wb)=(MC_(db))/(1+MC_(db))$

where, $MC_(wb)$ : moisture content in wet basis and

$MC_(db)$ : moisture content in dry basis

We now calculate the moisture content in wet basis:

$MC_(wb)=(MC_(db))/(1+MC_(db))$

$MC_(wb)=(0.90)/(1+0.90)$

$MC_(wb)$ = 0.474 = 47.4 % wet basis

➷ 1) Enzyme A

[This is because a pH below 7 is acidic and the optimum pH is 1 for this enzyme]

2) Enzyme C

[pH 7 is neutral]

3) Enzyme D

[A pH above 7 is 'basic']

4) Enzyme B

[It is still below 7 but it is closer to neutral so it is just 'acidic']
